More Details
Pyridine nucleotides play an important role in metabolism and, thus, there is continual interest in monitoring their concentration levels. Quantitative determination of NAD+/NADH has applications in research pertaining to energy transformation and the redox state of cells or tissue. Simple, direct, and automation-ready procedures for measuring NAD+/NADH concentration are very desirable. BioAssay Systems EnzyChrom™ NAD+/NADH assay kit is based on a lactate dehydrogenase cycling reaction, in which the formed NADH reduces a formazan (MTT) reagent. The intensity of the reduced product color, measured at 565 nm, is proportional to the NAD+/NADH concentration in the sample. This assay is highly specific for NAD+/NADH and with minimal interference (<1%) by NADP+/NADPH. Our assay is a convenient method to measure NAD, NADH, and their ratio.When tissue is used, should it be freshly obtained? Or is -80°C storage ok?
If direct sample processing is not possible, we recommend snap freezing tissue samples in liquid nitrogen and keeping them either in liquid nitrogen or at -80°C until further processing.
